7.   Is a muscle about the size of your fist   Weighs about one pound   Is behind and just to the left of the breastbone   Pumps about 5 quarts of blood every minute

8. The Functions of the Heart   Pumps blood through the lungs to remove CO 2 and refresh blood with oxygen   Pumps blood through the body to provide oxygen and nutrients remove waste products

9. The Pumping Heart

10. Blood Supply The coronary arteries are the blood vessels that supply blood and oxygen to the heart muscle.

11. Unhealthy Hearts Common Terms

12. 1. Atherosclerosis, Arteriosclerosis -Thickening/hardening of the arteries 2. Cardiovascular Disease, Heart Disease, Coronary Artery Disease -Common terms for heart disease

13. Common Terms 3. Myocardial Infarction, MI -Synonyms for “heart attack” 4. Asystole … Death

19. Cholesterol Heart Healthy HDL Heart Healthy HDL LDL <125 LDL <125

20. occurs in almost any artery in the body BUT When coronary arteries become blocked:   circulation decreases, which includes circulation to the heart muscle itself   cardiac muscle begins to fail

21. “The coronary arteries are the size of drinking straws and carry about 130 gallons of blood through the heart daily” (Clark, 119.) Blood Supply to the Heart

22. Atherosclerosis

24. How Does it All Fit Together? Coronary Artery Disease The most common and serious effect of aging  Fatty deposits build up, narrowing the passageway for blood  Atherosclerosis often leads to blockage of the coronary arteries  Heart attack

25. Signs and Symptoms  None: Silent Ischemia  Angina Pectoris: pain in chest, jaw or shoulder  Shortness of breath: sign of CHF, also swollen extremities  Heart attack: coronary artery becomes blocked and part of the heart muscle dies Signs & Symptoms None Chest Pain Shortness Of Breath Heart Attack

26. Screening and Diagnosis Stress Testmeasuresblood supply to h eart Cardiac Cardiac Catheterization Catheterization specificshows In arteries Narrowing Sites of EKG mea s ures electrical impulse

27.  Blood Tests  for cholesterol levels, kidney and thyroid function, presence of anemia.  Chest X-Ray  to show size of the heart, check for fluid around heart and lungs  Ejection Fraction (EF)  determines how well your heart pumps with each beat.
